Ce dernier est un polymère acrylique sensiblement dépourvu de carboxy, ou il contient un matériau comprenant au moins un composant caoutchouc de poids moléculaire élevé, ayant un poids moléculaire moyen compris entre 300000 et 2500000, et au moins un additif choisi entre les esters d'acides gras C12-C18, les monoglycérides d'acides gras C8-C10 et les esters de diacides C6-C10. Ces préparations percutanées ont d'excellentes propriétés en ce qui concerne l'absorption percutanée des médicaments, donnent des effets médicamenteux durables avec peu d'effets secondaires, et sont donc utiles pour la prévention et le traitement des menaces d'avortement, des naissances prématurées, ainsi que des troubles de la miction tels que l'incontinence urinaire, etc.
